Wie wir das erstellt haben
Covers external canister filters and hang-on-back (HOB) power filters for freshwater aquariums that a buyer comparison-shops in 2026, spanning budget (SunSun) to premium (Fluval FX6, OASE BioMaster Thermo) tiers. type is an enum: canister (fully sealed external unit, gravity/siphon fed) or hang-on-back (HOB; clips onto the tank rim, impeller-driven intake tube). tank_size_gal is the manufacturer's maximum rated aquarium size in US gallons; when the manufacturer publishes a min-max range, this is the top of that range. flow_rate_gph is the manufacturer's rated pump output in US gallons per hour — the raw pump figure, not a derated "in-tank filter circulation" number, when a source publishes both. media_capacity_l is the media basket/tray/canister filter-volume in liters as explicitly stated by the manufacturer; null when no liter figure is disclosed (common for HOB filters, which are usually specified by included cartridge/insert count instead). media_stages counts the manufacturer's own explicitly stated filtration-stage number (e.g. "4 STAGE FILTRATION" printed on AquaClear/Magniflow packaging, "5-stage" for the SunSun HW-304B) or, when no explicit stage count is published but the manufacturer names discrete filtration categories (mechanical/chemical/biological), the count of those named categories; null when neither is stated. wattage is the filter pump's rated power draw in watts at the 120V/60Hz US spec (or the single spec given, where regional variants exist); for the OASE BioMaster Thermo 850 — the one model here with a built-in heater — this is the pump only, the separate 400W heater element is called out in the product's provenance/priceNote instead of blended into wattage. self_priming is true only where the manufacturer explicitly describes an automatic/self-starting pump that needs no manual siphon step (e.g. Fluval's "Smart Pump" auto-start, a stated "self-priming pump", or a push-button primer described as self-priming); it is false where the manufacturer instead describes a manual hand-operated primer bulb/handle (Fluval's 07-series "Redesigned Primer" requires the user to hand-pump it); null where the manufacturer's page does not address priming at all. dimensions_in is length x width x height in inches as published, converted from mm/cm where the manufacturer only gives metric; cylindrical canisters are given as diameter x diameter x height. priceUsd is a representative current US street price (a named US retailer or the manufacturer's own USD listing) since most of these manufacturers' own product pages do not publish MSRP; null when no verbatim US-dollar figure could be sourced from a fetched page — several long-running EU-market products (OASE, both EHEIM Classic sizes) and two Fluval 07-series filters had no fetchable USD price and are left null rather than guessed. releaseDate is left null across the board: none of the fetched manufacturer or retailer pages stated a verbatim launch year/month for these long-running, frequently-restocked product lines, and none was fabricated.
